摘　　要：页岩气藏属于一种自生自储的非常规天然气藏,在进行页岩储层评价时,应重点考虑其含气性。根据湘西地区下寒武统牛蹄塘组页岩样品现场含气量测试数据及等温吸附试验结果,从含气量入手,针对有机碳含量、热成熟度、黏土矿物含量和石英含量等方面讨论页岩储层含气性影响因素。研究发现,含气量与有机碳含量呈良好的正相关关系,气体的吸附能力随热成熟度的增高有逐渐增大的趋势,同时含气量与黏土矿物含量呈一定的正相关关系,与石英含量呈一定的负相关关系。Shale gas reservoirs are self-generated and self-contained,gas-bearing characteristics should be focused on during reservoir evaluation. According to gas-bearing content testing data and isothermal adsorption results of shale sample from Niu Titang formation in lower Cambrian of western Hunan,discussesthe influential factors of shale reservoir on organic carbon content,thermal maturity,clay mineral content and quartz content. The study found that there is a good positive correlation between gas content and organic carbon content,and the adsorption capacity gradually increased with the increasing of thermal maturity,gas content and clay mineral content has a certain positive correlation,and there is a certain negative correlation between gas content and quartz content.
